This review highlights the light microscopic features of various infectious and non-infectious hair conditions and reports no new clinical results.

This review discusses the role of hair microscopy in diagnosing alopecia, stating that while it excludes diagnoses related to hair breakage, it only confirms nonspecific short anagen in alopecia cases.

This study found that UV stabilizers must diffuse uniformly and in high uptake levels throughout hair fibers during humidification cycles to effectively prevent photo-oxidative degradation.

This article presents a comprehensive overview of hair microscopy techniques and their diagnostic potential for systemic and cutaneous disorders, emphasizing its usefulness in resource-limited settings and highlighting the underutilization of this non-invasive method due to lack of awareness.

This review discusses the use of hair microscopy in diagnosing hair-related conditions, highlighting techniques and common applications, but presents no new experimental results.

The study found that pili bifurcati causes hair to intermittently split into two branches, each with its own outer layer.

In this study, hair anomalies associated with acrodermatitis enteropathica in a young girl improved significantly after two years of zinc therapy.

This study highlights confocal microscopy as a promising, minimally invasive tool for assessing hair morphology and internal structures, making it valuable for cosmetic hair assessments.

This research suggests that both proposed pathways into hair fibers for molecule penetration are valid and complementary, with all fiber structures acting as potential routes for delivering materials.

This study found that multiphoton microscopy effectively visualizes the microstructure of in vivo mouse skin, offering a clear view of various skin layers and components like corneocytes and collagen fibers.

This study found that electroosmotic flow through hair follicles significantly contributes to solution flow during iontophoresis in hairless mouse skin.

This study found that the TrichoScan method detected significant increases in hair counts and cumulative hair thickness in men after finasteride treatment, suggesting its potential for monitoring hair treatment responses.

In this study, researchers used three-dimensional reconstruction to show that the shape of the hair follicle determines the hair's form, with variations observed among different racial groups.

This study developed an objective standard grading system for evaluating hair damage using scanning and transmission electron microscopy.

This study observed that hair casts, seen in girls with tightly drawn hairstyles, may result from local circulatory disturbances and scalp inflammation.

This study found that mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

Hair transplant complications were likely due to deep graft placement and rough handling.

In this study, researchers showed that multiphoton microscopy with fluorescent protein tagging enables single-cell imaging and tracking in live transgenic mice, offering new insights into cell dynamics in stem cell research compared to traditional histological methods.

In this study, fluorescence microscopy revealed that a cationic cellulose ether derivative adsorbed onto hair fibers desorbed significantly when treated with sodium dodecylsulfate.

In this study, pediatric hair and scalp disorders were effectively diagnosed using trichoscopic and light microscopic examinations, demonstrating high agreement with clinical diagnoses and emphasizing their utility as reliable, non-invasive diagnostic tools in a hospital-based setting.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

This article reviews the rationale and science behind forensic hair examinations and discusses the role of microscopic and DNA techniques in differentiating hair sources but reports no new findings.

In this study, researchers found that using a handheld digital microscope, hair diameter was a better determinant of perceived alopecia severity in androgenetic alopecia than hair density.

This study observed that the glassy layer of hair follicles in guinea pigs consists of thick collagen-type fibrils organized into two distinct arrays, whereas in young mice, the fibrils are thinner and develop between the outer root sheath and fibroblasts.

This review discusses the genetic disorder, monilethrix, characterized by fragile, brittle hair and its inheritance patterns, and reports no new clinical results.

Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.

The document describes a method for preparing hair for microscopy by embedding it in plastic, cutting it, and storing it cold before imaging.

In this study, researchers found that a high-cost hair restoration product containing coconut oil and glycerol effectively restored the structural integrity of chemically processed hair, particularly in samples that were significantly damaged by bleaching and color treatments.

This study found that in vivo confocal scanning laser microscopy accurately quantifies neogenic hair follicles in mice, producing results similar to histology while avoiding fixation artifacts.

This study found that aging in Korean individuals is associated with changes in hair diameter and surface structure, as observed through atomic force microscopy.
